I'm creating a Vehicle this way:
float front_dir[3] = {0,1,0};
float up_dir[3] = {0,0,1};
float vl_tirepos[3] = {10,5,-5};
vehiclejoint = CreateCustomMultiBodyVehicle(&front_dir, &up_dir, truckbody);
This works without problems, the body falls down. But, if i try to add tires, the vehicle-body disapears.
vl_joint = CustomMultiBodyVehicleAddTire(vehiclejoint ,0,&vl_tirepos, 10, 30, 10, 10, 100, 100);
I have tried many different values, but its allways the same problem...
